That is pretty darn impressive, 1400 degrees just right at the sweet spot.You can really see gasification taking place.Really very nice.

My thoughts now since we are seeing more and more a move towards using refractory materials that consideration would be to forming the firebox and riser tube separately that can be joined and replaced as things wear our or burn out.If you already considered this in your build and I missed that I apologize.

This really is exciting, this is something that can be easily adapted around the world no matter what your status is.

ive been looking at making a former for them and the way i see it its either do ppottys way or splt the cast into 2 halfs

there is another way a riser tube and a burn box thats seperate and this is the way im going the burn box is easy to make the riser tube is not however can be split again so its 3 seperate parts to the build

making the former for the inside is not easy but i think ive come up with a way to do it so its expandable to different sizes

the problem is seperating the form from the mold ppottys is very ackward to do and i think ive solved it the outer shell is easy to do and should seperate easily
